Description

Ignition voltage capacitor ignition process and systems built afterwards for internal combustion engines. (Z x Z) = ignition voltage capacitor - ignition.

The invention has the object to disclose a new ignition method at which a contactless impulse with the least amount of time lost also contactless controlled high-voltage switching element is supplied, which is in the desired Moment the stored energy directly charged to the ignition voltage of a capacitor is discharged to the respective spark plug.

Systems of this type avoid all components that are in place during the Consumption depending on the engine operating time.

Since only one capacitor acts as an energy store, it can be charged quickly and is then discharged directly and without contact to the spark plug, its charging voltage and its stored energy is dosed exactly or approximately in this way by a charging unit as it is for the consumer, i.e. the spark plug as the ignition element, the most appropriate is.

Fig.l.

Fig.l (= Fig.l) shows a block diagram in which the above Process by means of electronic components can be executed.

The current of a battery 1 or some other power source is over the switch 2 at the connection point 7 is fed to a charging unit 20 Way, an alternating voltage is generated, which is fed to a rectifier 6 at point 4 which charges the storage capacitor 7 to the desired ignition voltage.

The capacity of this storage capacitor 7 is expedient designed so that they are 16,17 on the respective spark plug.

18 and 19 or more, in spite of the or the locking member 10, here e.g. a high-voltage diode and the switching element ll. related to the spark plug 17 the provides the desired ignition energy a @.

Fig.2 in Fig.2 shows a contactless pulse generator, the in connection with the device according to the block diagram of Fig.1 Fig.1 as follows functions.

The disk 31, which is used e.g. in 4-stroke engines with half the crankshaft speed rotates, has a passage opening 32.

The steel source 33, one per spark plug, radiates through the opening 32 to the control pulse cell 9, 11, 13 or 15, whereby the capacitor 7 over the Lock 8,10,12 or 14 to the respective spark plug 16,17,18 and 19 is discharged.

The speed and load-dependent ignition timing adjustment is also used here initially in a known manner via the centrifugal governor of the components 36,37,38,39,40 and 41 is reached, while elements 34 and 35 are the radiation sources due to the negative pressure 33 adjust to the required position depending on the load by turning 42 is fixed at 34.

Fig.2 The radiation generator according to Fig.2 thus replaces the. Ignition contact breaker and the high-voltage distributor. The component 42 is completely shielded from the outside and contains the photodiode switching against rays 9, or. 11, 13 or 15, the connection contacts 8,10,12 and 14 lead to the high-voltage periods with the same identification numbers, while the outputs to the spark plugs 16, 17, 18 and 19 are connected.

The magnet 43 with the shaft 41, corresponding to the shaft 41 also the Fig.2, generates the pulses in the coils, which in a known manner in the pulse formers 27,28,29 and 30 in control pulses to the thyristors 8 + 9,10 + 11,12 + 13 and 14 + 15 of the Fig.la Fig.la are reshaped and these thyristors ignite, thereby creating the capacitor 74, or 73 or 72 or 7 is discharged and the sparks jump over the candles High voltage thyristors 8 + 9,10 + 11,12 + 13 and 14 + 15 switch the ignition voltage directly, whereby the time span from the first impulse to the ignition spark becomes extremely short and also for the first time all switching operations are made contactless, so that there are no more parts, the slowly or otherwise wear themselves out during operation and thus their function the ignition system continuously deteriorate.
